Hello, Whats the progress and status on this... Assesing its integration with https://github.com/DefGuard/defguard

with a Discussuion here

@compgeniuses I haven't worked on this in a while. Status is still the same, what still needs to be done:

• Heavily manual testing
• Bump allauth to latest version
• Rebase and resolve conflicts

I don't have plans to work on this in near future, unless there is a financial incentive then I can put in my schedule (as mentioned here: https://github.com/chiefonboarding/ChiefOnboarding/issues/437#issuecomment-2027464986).

It would be good to get this checked by a second developer as it's auth based stuff, which is always a bit tricky. That person would also be paid from the donation to get this finished.
